    Violent Shaking, but strictly @ 1600-1800rpms

    Pardon no update. Back wrenching this week and should report back after backing-off spring adjuster soon. Re last reply: "gas", "plugs, wires"??? The only possible commonality with this Cummins thread would be trans and I had mine pro rebuilt with a HD Goerends torque converter. Sorry, no help...

    1st post: all respect to the grey and grizzly! My first Cummins. Wrenched on many of my prior Ford 6.9/7.3 idi's, P-strokes, etc. Minor Soob expert. Just bought a '97 2500 4x4, 47re, ext. cab. 350k miles. Price was low due to a very particular shaking problem. Conditions: Only between...
